NHTSA recall 21V944000
Electrical System · Hyundai Motor America
Details
What's wrong: An unstable electrical ground may cause the vehicle to enter a fail-safe mode with reduced acceleration and power. In certain conditions while in fail-safe mode, the vehicle may accelerate after the gas pedal is released.
Why it matters: Unexpected acceleration following gas pedal release can increase the risk of a crash.
The fix: Dealers will update the epcu (electric power control unit) software and repair the ground wiring, free of charge. Owner notification letters were mailed February 9, 2022.
